I know you can couple a 1050 with a 750 and use the 1050 to drive the rear channel in 6.1 and was curious if anyone has done this and if you can do it with the 770?

I'm looking to bump up to 6.1 as I have a matched center to my Klipsch RF-3s that I can use for the rear channel that I used with my 1050 with a direct 5.1 feed with myold DVD player (since upgraded so no 6.1).

Thoughts or suggestions?
